Added stats page

Sorry for the monolithic commit.

Integrated the stats page with the project. I got my data converter under test and am looking into getting karma set up to test the angular components. I also added a /api/ endpoint to expose raw JSON which I am not confident is the way we want to move forward. I'd definitely appreciate any feedback you have there.

I also added the .compress middleware to express. this brings the JSON transfer size down from ~500k to ~25k.

I also converted the main stats page from HTML to jade, which I find to be awesome to write, I'm considering converting my angular templates and exposing them through the service.
